Title: Actuator for moving in vertical direction
Inventor: KAWASAKI KATSUYOSHI
IPC: G11B7/09
Filed: 1993-05-12
Abstract: PURPOSE:To improve the followup ability for the ruggedness on a disk by supporting the weight of a matter by impressing a DC current through a first coil and displacing the matter in a vertical direction by impressing an AC current through a second coil. CONSTITUTION:The control of the AC current for controlling the displacement amount of a write head is performed by feeding back the current flowing through the second coil 12c to a controller 23. The variable amount of the current flowing through the coil 12c becomes sufficiently large, and the change in a current value is obtained in high precision, and by controlling the displacement amount of the write head precisely, a distance between the write head and a disk is fixed always. Further, the DC current for making flow a driving current I dealing with the weight is impressed through the first coil 12b for supporting the weight of the write head, etc., by a control circuit 24. Further, a Zener voltage Vz, a current detection resistor R and the thrust constant KE of a voice coil motor 7 required for providing such a current I are decided by using the relation KE=Vz/R=Mg.

IPC: H01S5/023
Filed: 1980-09-23
Abstract: PURPOSE:To readily assemble a semiconductor light emitting element by etching the edge lines of two surfaces crossing with one another at the front surface side of a heat sink soldering the element along the edge line, chamfering it and soldering the element so that the light emitting end face of the element and the front surface  of the sink become in the same plane. CONSTITUTION:The edge line of two surfaces crossing with one another at the front surface side of a heat sink carrying a semiconductor laser 2 is etched along the edge line, and a chamfering part 7 is formed. The light emitting end face 4 of a laser 2 is diposed at the chamfering part 7, and the light emitting unit 3 and the sink 2 are secured to one another by soldering while maintaining the light emitting unit 3 and the side face of the sink 1 in the same plane. Since the chamfering part 7 is produced with rounded chamfering unit 7' in this manner, solder 5 is sufficiently flowed to eliminate the cavity or the like, and even if the position of the laser 2 is slightly displaced, the fluctuation, shortcircuit and leakage of the emitted light can be remarkably reduced.

Title: Sensor for inclination and acceleration
Inventor: TAKURA TOSHIYASU
IPC: G01P15/11
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To detect both an acceleration and an inclination with good accuracy by using one sensor, by a method wherein the movement direction of a permanent magnet is regulated to one direction by using a leaf spring. SOLUTION: A support base 5 is attached to the frame of an object to be detected such as a motorized bicycle, a motorized wheelchair or the like, in such a way that a leaf spring 6 becomes vertical. When the object to be detected is tilted forward or backward by an angle θ, also the support base 5 is tilted, the leaf spring 6 is deformed, and the position of a permanent magnet 9 is displaced with reference to a magnetoresistance element 11. It is assumed that, when the object to be detected is in a horizontal state, a constant output is generated. Then, an output voltage is decreased when the permanent magnet 9 is displaced to the front direction as shown in Fig. 2b, and when the permanent magnet 9 is displaced to the rear directions shown in Fig. 2c, the output voltage is increased.  When an acceleration exists in the movement direction of the object to be detected, the permanent magnet 9 is moved to a direction opposite to a direction in which the acceleration acts. As a result, the acceleration can be detected in the same manner as a case in which the object to be detected is tilted.
